Dim scores(30) As Double

the number 30 designates which of the following?
(A)

(A)
(B)
(C)
(D)
6.

It is invalid since more than one array is dimensioned by a single Dim statement.
It is invalid since the two arrays must have the same data type.
The subscripts of states range from 1 to 49.
The subscripts of populations range from 0 To 49.
D
